SPECIFICATION forming ar of Letters Patent No. 588,782, dated August24,1897.

' ilpplication filed March 25, 1897.

i the city and county of Philadelphia, State of Pennsylvania, haveinvented an Improvementin Paper-BagMachines, of which the following is aspecification.

My invention has reference to combined tube formingand printingmachinesfor paperbag manufacture; and it consists of certain improvements whichare fully set forth in the following specification and shown in theaccompanying drawings, which form a part thereof.

' The object of my invention is to provide a suitable apparatus forautomatically forming and printing tubes from a roll of paper whichshall be in complete forinfor finishing by hand,'the said finishingoperation consisting in the folding and pasting of the satchel-bottom incompleting the bag. In hand-made bags it has heretofore been customaryto first cut the sheet in the proper form with the recess at one end "tocorrespond to the thumbnotch, and while in the flattened condition toprint the name or advertisement upon the middle or surface correspondingwith one side of the bag, and subsequently to fold and paste the saidpaper sheet in the form of a tube, and, finally, to fold one end thereofin the form of a diamond fold and, finish the scaling to produce asatchel-bottom. Bags of this character command a greatly increased priceover what are known in the trade as machine-made bags, first, becausethe satchel-bottom is usually more perfect, and, secondly and moreparticularly, because 'the printing may be performed in a most perfectmanner, since it can be accomplished by means of flat beds and type onimproved printing-presses. Furthermore,the open end of the bag is cutacross and formed with a notch on sharp clean-cut lines, which arecharacteristically different from the serrated or rough'cuts invariablyfound upon machinemadebags.

e In carrying out my invention I am enabled v to retainall of theadvantageous features of the hand-made bags, while at the same time theformation of the tube and printing oper- Serial No. 629,202. (No model.)

ations are carried on automatically and at a greatly-reduced expense. Tosecure this result, I employ a tube-forming machine provided withpunching-dies and cutting-0E cutters arranged at considerable intervalsapart in the machine, the former being adapted to cut the thumb-notch,while the latter compietely severs the tube into lengths across theterminals of the 'curved line.previously punched and corresponding tothethumbnotch, and with said mechanism is combined at an intermediateposition a printing-press formed with a fiat platen and type-form, andfurther provided with a flexible impressiontongue, over which the tubepasses'and which directly presents a fiat surface under the smooth sideof the bag-tube to receive the impression from the type.

My improvements furthermore contemplate adjustability in the tube-formerto correspond to difierent widths of tube to be formed,- and also arelative adjustment between the thumb-notch dies and the cutting-offcutters to compensate for different lengths of bag-tube. These variousimprovements contemplate details of construction, all of which will bemore fully understood by reference to the accompanying drawings, inwhich'- Figure 1 is a side elevation of a tube forming and printingmachine embodying my invention. Fig. 2 is a plan view ofsame with aportion of the feed-rollers and upper part of the printing-pressremoved. Fig. 3 is a longitudinal section of myimproved machine on line5 5 of Fig. 2. Fig. 4 is a transverse section of same on line 1 1 ofFig. 3. Fig. 5 is a transverse section of same on line 4: 4 of Fig. Fig.6 is a transverse section of same on line 2 2 of Fig. 3. Fig. 7 is atransverse section of same on line 3 3 of Fig. 3. Fig. 8 is a sectionalview of a detail of Fig. 1 on line 6 6. Fig. 9 is a perspective view ofthe tube in the process of being formed, out, and printed. Fig. 10 is alongitudinal section through same. Fig. 11 is a perspective view of thefinished tube with printed advertisements upon it; and Figs. 12 and 13are similar views showing the forming of the bottom upon the tube, whichare subsequently produced by hand operations.

A is the main frame.

B is the tube-former, which is connected at one end of the said frame atb and provided with lateral sides B, hinged to the formerbody by linksI). These links may have sufficient friction to hold them in anyadjusted position. Guides m and m may be employed with the said lateralguides B to insure the paper being folded about the former. Theadjustment of the width of the parts B, m, and 777. controls the widthof the bag.

C represents the thumb-notch punching devices and are arranged so as tooperate through an aperture in the former.

C is the punch-plate and is curved to correspond to the curve to, Fig.9, and C is the punch, the descent of which severs the paper tube on acurved line, as indicated in said Fig. 9. The punch-plate is held in asuitable frame 0, so as to have a fixed position,while the punch C isvertically movable in said frame under the action of a pivoted lever G,which is operated by a link 9 and reciprocating arm G, pivoted to themain frame at G The frame C is adjustably supported upon the main frameA and guided longitudinally thereon parallel to the former B. It isadjusted by means of screws (J and may be firmly held in position bymeans of clamping bolts 0. To compensate for this adjustment of theframe 0, the arm G is made slotted at its free end, so that theconnection with the rod g is likewise adjustable. By adjusting the frame0 upon the main frame A the connection of the rod 9 with the arm G isautomatically moved in the same direction while maintaining itsoperative position.

D D are a pair of feed-rollers carried on the main frame and gearedtogether, so as to have the same surface speed, and are provided attheir middle portions with recessed parts (1 to permit the passage of anextension of the former, and which is adapted to sustain theimpression-tongue of the printing-press, to be described later.Furthermore, the recessed portions cl prevent excessive pressure uponthe pasted fold of the tube. It is preferable that these rollers shallbe pressed to-' gether under the action of springs (Z, the tension ofwhich may be adjusted. These rollers are driven by means of aratchet-wheel I and reciprocating pawl 1 the latter being carried by apinion I, which is rotated alternately in opposite directions by meansof a reciprocating rack'segment H, pivoted to the main frame at h. Thisrack-segment is rocked by means of a link R operated by a crank rupon agear B. This gear R meshes with the rod R with the racksegment 1-1 at7L2 to increase or decrease its leverage the extent of rotation andfeeding action of the rollsD D may be varied to suit different lengthsof bags. This may also be secured by adjusting the crank-pin 1" upon thegear R in any well-known manner, the radial slot for such adjustmentbeing clearly shown.

During the reciprocation of the rack II a spring-pawl H, carried by thearm G, is operated upon by a cam G on the said rack H and causes the armto be lifted gradually and thereby operate the punch-die C and then tofall, suddenly withdrawing the said punchdie, so as to permit the tubeto be fed. The pawl H is held outward into operative position by aspring h, and has a beveled face, which upon the return stroke is struckby the cam G on the rack I-I andpressed inward, so that it does notraise the arm G. In this manner a full reciprocation of the rack Hproduces a single and quick operation of the arm G. This is essential,since the punching operation must take place rapidly and leave the tubeB to be fed upon the reciprocation of the segment H. At the other end ofthe machine is arranged the cutting-off cutter devices F.

J is a stationary cutter, and J isa vertical reciprocating cutter. ThecutterJ is secured to an adjustable frame F, which is adjustable overthe main frame A under the action of adjusting-screws M, so that thecuttingoff cutters may be adjusted to or from the punching-dies. Theframe F is provided with upright guides F in which averticallyreciprocating transverse frame F is guided, and which carriesthe verticall y-reciprocatin g cutter J. This frame F is connected ateach end with a link it. links are adj ustaoly connected to pivoted armsK, pivoted at 71: and having arms K, which are operated by cams L uponthe powershaft 1". Suitable springs Z are employed to raise the arms Kand also the frame F when permitted by the cams L.

The arms K are provided with horizontal slots M, sirnilar to the slot inthe arm G, to permit the adjustment of the connection with the links 7owhen the frame F" is adjusted longitudinally upon the main frame A..

Clamping-bolts f, operating through slots in the bed-plate or mainframe, may be employed to clamp the frame F in its adjusted positions. Astripper-platej is employed immediately above the cutter J to hold downthe tube during the rising of the cutter J. The operation of thecutting-off cutters J J is to produce the transverse cut it, (indicatedin dotted lines in Fig. 9,) so that it crosses the terminals of thecurved or irregular punched portions it in such a manner that the smallpiece of paper a is completely severed by the combined action of thepunch and cuttingoff cutters and falls away to leave the thumbnotch, asshown in Fig. 11. By this combined The free ends of the action of thepunch and cutters a smooth-cut open end of the tube is secured, and theend of the tube to be formed into the bottom is also made with a cleantransverse out, which is characteristic of hand-made bags and especiallydesired by the trade.

In machine-made bags it has been customary to produce a serratedseverance of the tube in such a manner as to produce a thumbpiece and anextension, respectively, upon two adjacent tube-sections; but in thiscase the extension corresponding to the piece cut out from thethumb-notch of the adjacent tube-section is left upon the bottom andmust be properly pasted and is otherwise objectionable. In my improvedmachine herein set out this is obviated, and the piece removed in theformation of the thumb-notch is completely eliminated from thetube-sections.

Interposed between the feeding-rolls-D and the cutting-off devices F, Iarrange a printing-press E, preferably of the -flat-bed type, as shown.Referring to the construction here illustrated, E is the impression-bedor platen, and this is adjusted upon the arms E pivoted at e to the mainframe by adjustingscrews 6, the object of which is to level the platenand adjust it to or from the type-bed N. The power-shaft r is providedwith two cams T, which operate upon the arms E to raise or lower theplaten. The type-form bed N is pivoted upon a transverse shaft- 71,secured to the main frame A, and is movable to and from the platen bymeans of links S, transverse shaft W, and cranks 3 upon the gears R ofthe power-shaft a".

N represents the type, which is secured in the type-form and clamped tothe bed N in any suitable manner. i

O is the ink-table and is carried by the type-bed.

P are the inking-rollers and are pivoted to a transverse shaft 19, journaled to the arms P carried upon the transverse shaft W. A spring Pinsures the inking-rollers traveling over the ink-table and type-formwhen the parts are operated. Links N connect the arms P and the mainframe. It will now be observed that as the cranks s raise the shaft Wthe type-bed is lifted, and simultaneously the arm P is rocked and theinking-rollers pass down over the type of the type-form. When thisoperation is taking place, the platen is lowered. When the reverseoperation takes'place, as indicated in Figs. 1, 3, and 4, the printingtakes place upon the paper-tube which is intermediate of thefeeding-rolls and the cutting-off devices. Furthermore, this printingoperation is with a flat impressionsurface. j

The platen E is provided with a longitudinal groove 6, extending throughit upon its upper surface, and arranged above the platen andintermediate of it and the typeform bed is an impression-tongue 13 whichis detachably connected to the extension of said groove.

constitutes a completed tube.

the former B. The impression-tongue is of a width substantially equal tothe width of the bag-tube, but may be 1ess,'if desired. It is of greaterwidth than the groove ein the platen, so as to rest upon the platen ateach side of the This impression-tongue may be changed with each changein the width of the tube made and printed. This impressiontongue is,furthermore, the real impressionsurface upon which the printing isperformed and is that upon which the make-ready may be made. The tubemoves over this impression-ton gue freely when the platen is lowered andthe type-form bed raised, and when the printing is to take placethe'paper remains stationary, while the type-form bed is lowered intoposition immediately above the paper and the platen E raised, so as tooperate upon the under side of the impression-tongue and press itagainst the type of the type-form bed, producing a most perfectimpression and thereby imparting a high finish to the printing upon thetube. Furthermore, the pasted seam of the tube is received in the grooveof the platen and is not subjected to excessive pressure, which mightsqueeze out the paste. Furthermore, the double layer of paper and pasteplay no part by obstructing or interfering with the printing, as thisoperation takes place upon the smooth side of the tube and between aperfectly-flat impression-surface and the type. The impression-tongue,furthermore, performs a function of holding and guiding the tube inproper position irrespective of the movements of the platen andtype-form bed.

In the operation of the machine the web of paper is fed from a roll andpaste applied to one edge in any suitable manner, and sucha web isdelivered to the former B of my improved machine. During the passage ofthe web over the former the free sides are bent downward by gravity andunder the action of the guides m and m, the guides m being so formed asto permit the pasted side of the tube to clear the stationarypunch-plate C and its support. When the tube reaches the feed-rollers D,it has been overlapped and While the tube is being fed through themachine, the punch-dies O C operate to punch the curved or irregular outa simultaneously or there-,

about with the action of the cutting-off cutters J J; but intermediateof these cutters and punches the tube will have been formed with one ormore of such curved cuts to, as clearly shown in Figs. 9 and 10. Theoperation upon the tube to feed it is an intermittent one, so that thetube is fed a distance corresponding to the length of the tube-sec-Hon-namely, the distance between two such curved cut-s uand when this isdone the punchingof a new out a and the severing upon the transverse outto (see dotted lines, Fig. 9) takesplace, and at the same time theprinting, as at X, is performed. When these three operations areaccomplished, the tube is at rest, and consequently the printing, aswell as the cutting, is produced in the most perfect and clean manner.With each punching for the thumb-notch upon one portion of the tube toconstitute one tube-section the printing devices are printing upon aportion corresponding to another tube-section, and the cutting-01fdevices are severing a completed tube-section from the extreme end ofthe tube.

While I prefer the construction shown, it is evident that the variousdetails may be modified without departing from the spirit of theinvention. I do not confine myself to any particular details of theprinting-press m echanism, as this may be greatly modified whilesecuring the same general advantages;
